Mantoverde-Santo Domingo district integration

The Plan presents the opportunity to unlock a total of $80-100 million per year in operating cost savings, while also enabling additional copper and cobalt production – with strategic by-product sulphuric acid production used to treat district copper oxides and fill excess SX-EW capacity, infrastructure capital savings, and the potential for ...

Production of cobalt from copper-cobalt ores on the …

It is estimated that the Copperbelt contains 5 billion tonnes of ore containing 3.3% copper, yielding 185 million tonnes of copper. Industrial-scale mining on the Copperbelt has taken place for over a century. Cobalt is produced as a by-product of this copper mining. However, the increasing demand for energy storage and electric …

Metal Allergy Symptoms and Contact Dermatitis

Metals including nickel, chromium, cobalt chloride, copper and gold are common triggers for eczema, particularly contact dermatitis. Contact dermatitis happens when the skin becomes irritated or inflamed after coming into contact with a substance that triggers an allergic reaction.
